DETAILED DESCRIPTION OF EMBODIMENTS

Selected embodiments will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.

Referring initially to FIG. 1, a vehicle 10 is illustrated in accordance with a first embodiment. As shown in FIG. 2, the vehicle 10 includes a vehicle body structure 12 that defines a cargo area 14 with a shelving arrangement 16 that is described in greater detail below. The vehicle body structure 12 has, among other elements, a floor structure 20, a first side wall structure 22, a second side wall structure 24 and a roof structure 26.

The floor structure 20, the first side wall structure 22, the second side wall structure 24 and the roof structure 26 define a rear hatch opening 28 that is covered by a rear door 30 that moves between an open position (not shown) and a closed position (FIG. 1) covering the rear hatch opening 28. In FIG. 2, the rear door 30 has been removed to reveal the cargo area 14.

A rear seat assembly 32 is attached to the floor structure 20 in a conventional manner, as shown in FIGS. 2, 4 and 5. For example, the rear seat assembly 32 can be attached to the floor structure 20 with removable fasteners (not shown). The rear seat assembly 32 includes a seat cushion 34 (FIGS. 2 and 5) and seatback 36 (FIGS. 4 and 5), which include seatback sections 36 a, 36 b and 36 c (FIG. 4). The seatback 36 (and individual seatback sections 36 a, 36 b and 36 c) are movable between an upright orientation shown in FIGS. 5 and 34, and a folded orientation shown in FIG. 44.

As shown in FIGS. 4 and 19, the floor structure 20 also includes sill section 38 that partially defines the rear hatch opening 28.

The cargo area 14 is located rearward of the seatback 36 of the rear seat assembly 32 with the seatback 36 in the upright orientation. When the seatback 36 is moved to the folded orientation, the cargo area 14 is extended such that cargo can be placed on the upwardly facing surface of the seatback 36 (in the folded orientation). The cargo area 14 is further defined within the vehicle 10 between the first and second side wall structures 22 and 24, above the floor structure 20.

As shown in FIGS. 3-5 and 18-19, the floor structure 20 has an upper surface 40 that includes a concaved area defining a concealed cargo space 42 sufficient to receive a spare tire 44. The concealed cargo space 42, as shown in the drawings, is a circular shaped concaved area that is shaped to receive the spare tire 44, but can alternatively have a differing shape in order to store additional vehicle related elements. As shown in FIG. 5, the concealed cargo space 42 is concealed below the shelving arrangement 16. Specifically, a deck panel 46 is dimensioned and shaped to overlay and cover most of the upper surface 40 of the floor structure 20. Further, the deck panel 46 extends along the bottom of the cargo area 14.

As shown in FIG. 4, the floor structure 20 also includes four tether clips 48 that are rigidly fixed in position by, for example, mechanical fasteners. The tether clips 48 and tethers T are described in greater detail below with reference to FIGS. 18-20. The tether clips 48 are hidden beneath the deck panel 46. However, the deck panel 46 includes tether recesses 46 a and 46 b, as shown in FIG. 6. The tethers T extend through the tether recesses 46 a and 46 b.

A description of the shelving arrangement 16 is now provided with specific reference to FIGS. 8-33. The shelving arrangement 16 is basically defined by the first side wall structure 22, the second side wall structure 24, a forward shelf 50 and an aft shelf 52. As is described in greater detail below, the first and second side wall structures 22 are configured to support the forward shelf 50 and the aft shelf 52 in a variety of positions. In the positions shown in FIG. 7, the forward shelf 50 and the aft shelf 52 completely cover the floor structure 20 and the deck panel 46. With the forward shelf 50 and the aft shelf 52 in other positions (described below), portions of the deck panel 46 can be exposed, as described below.

The first side wall structure 22 can include a plurality of elements, such as an outer side panel and an inner side panel. However, for purposes of understanding the shelving arrangement 16, description of the first side wall structure 22 is directed to an interior surface 60, as shown in FIGS. 8 and 10. The interior surface 60 of the first side wall structure 22 extends upward from a first side the floor structure 20 within the cargo area 14. The interior surface 60 includes a plurality of protrusions and adjacent recesses that together define a plurality of surfaces that are further described below.

The second side wall structure 24 can similarly include a plurality of elements, such as an outer side panel and an inner side panel. However, for purposes of understanding the shelving arrangement 16, description of the second side wall structure 24 is directed to an interior surface 62, as shown in FIG. 9. The interior surface 62 of the second side wall structure 24 extends upward from a second side of the floor structure 20 (opposite the first side) within the cargo area 14. The interior surface 62 also includes a plurality of protrusions and adjacent recesses that together define a plurality of surfaces that are further described below.

The interior surface 60 of the first side wall structure 22 and the interior surface 62 of the second side wall structure 24 face one another and are symmetrical with respect to one another. Put another way, the interior surface 60 and the interior surface 62 are identical to one another except that they are mirror images of one another. More specifically, each and every contour and shape of the interior surface 60 of the first side wall structure 22 is present on the interior surface 62 of the second side wall structure 22, except that the interior surface 62 is a mirror image of the interior surface 60. Therefore, the description below of the interior surface 60 of the first side wall structure 20 equally applies to the interior surface 62 of the second side wall structure 24. Consequently, for the sake of brevity, only the features of the interior surface 60 are described below, but apply equally to the interior surface 62.

More specifically, the various projections, recesses, surfaces and surface contours of the interior surface 60 described below are also provided on the interior surface 62 of the second side wall structure 24. The surfaces and surface contours of the interior surface 60 are aligned with the corresponding surfaces and surface contours of the interior surface 62. Consequently, the interior surface 62 of the second side wall structure 24 is provided with reference numerals identical to those of the interior surface 60 of the first side wall structure 24 since they function together.

As shown in FIGS. 8 and 10, the interior surface 60 (and the interior surface 62 in FIG. 9) is provided with a plurality of first or forward shelf supporting surfaces 70, 72 a, 72 b, 74 a and 74 b, a plurality of forward shelf guiding surfaces 80 a, 80 b, 80 c, 80 d, 80 e, 80 f, 82 a, 82 b, 82 c, 82 d, 82 e, 82 f and 82 g, a plurality of second or aft shelf supporting surfaces 90, 92 a, 92 b, 94 a, 94 b, 94 c, 94 d and 94 e, and a plurality of second or aft shelf guiding surfaces 96 a, 96 b, 96 c, 96 d, 98 a, 98 b, 98 c, 98 d and 98 e. The forward shelf supporting surfaces 70, 72 a, 72 b, 74 a and 74 b all extend in a generally horizontal direction and face upward and are dimensioned to support the forward shelf 50, as described further below. The aft shelf supporting surfaces 90, 92 a, 92 b and 94 a all include at least a surface portion that extends in a generally horizontal direction and face upward. The aft shelf supporting surfaces 90, 92 a, 92 b and 94 a are dimensioned to support the aft shelf 52, as described further below. The aft shelf supporting surfaces 94 b, 94 c, 94 d and 94 e all include at least a surface portion that extends in a generally vertical direction.

The forward shelf supporting surface 70 of each of the interior surface 60 of the first side wall structure 22 and the interior surface 62 of the second side wall structure 24 together define a lower retention location 110, as shown in FIG. 11 for supporting the forward shelf 50. The forward shelf supporting surfaces 72 a and 72 b of the interior surface 60 of the first side wall structure 22 and of interior surface 62 of the second side wall structure 24 together define a middle retention location 112 (FIG. 12) for the forward shelf 50. The forward shelf supporting surfaces 74 a and 74 b of the interior surface 60 of the first side wall structure 22 and of interior surface 62 of the second side wall structure 24 together define an upper retention location 114 (FIG. 13) for the forward shelf 50. As is described in greater detail below, the forward shelf 50 is easily moved between the lower retention location 110 and the middle retention location 112 and easily moved between the middle retention location 112 and the upper retention location 114 due to the shape and contours of the plurality of forward shelf guiding surfaces 80 a, 80 b, 80 c, 80 d, 82 a, 82 b, 82 c, 82 d, 82 e, 82 f and 82 g.

As shown in FIGS. 14 and 15, the plurality of forward shelf guiding surfaces 82 a, 82 b, 82 c, 82 d, 82 e, 82 f and 82 g, define a first movement path with positions 120 a-120 b-120 c between the middle retention location 112 and the upper retention location 114. Specifically, when the forward shelf 50 is to be moved from the upper retention location 114 to the middle retention location 112, the forward shelf 50 is lifted to the position 120 a (an inclined orientation), then pulled rearward to the position 120 b (an inclined orientation), as shown in FIG. 14. The guiding surface 82 d prevents forward movement of the forward shelf 50 during this repositioning operation. The forward shelf 50 then contacts the guiding surface 82 f and can be slid down along the guiding surface 82 f to the position 120 c shown in FIG. 15. The forward shelf 50 contacts the forward shelf supporting surface 72 a and can then be slid forward to contact the forward shelf guiding surface 82 a, then dropped into the middle retention location 112, as shown in FIG. 15. In order to move the forward shelf 50 from the middle retention location 112 to the upper retention location 114, the reverse movements are performed with the plurality of forward shelf guiding surfaces 82 a, 82 b, 82 c, 82 d, 82 e, 82 f and 82 g guiding and limiting movement of the forward shelf 50.

As shown in FIGS. 16 and 17, the plurality of forward shelf guiding surfaces 80 a, 80 b, 80 c and 80 d define a second movement path with positions 122 a-122 b-122 c between the middle retention location 112 and the lower retention location 110. Specifically, as shown in FIG. 16, the forward shelf 50 is lifted from the middle retention location 112 to the position 122 a (an inclined orientation), is then pulled rearward to the position 122 b where the forward shelf 50 contacts the guiding surface 80 e. Thereafter, as shown in FIG. 17, the forward shelf 50 is moved along the guiding surface 80 e to the position 122 c (an inclined orientation) when the forward shelf 50 contacts the guiding surface 80 a. Thereafter, the forward shelf 50 can be dropped into the lower retention location 110 onto the forward shelf supporting surface 70. In order to move the forward shelf 50 from the lower retention location 110 to the middle retention location 112, the reverse movements are performed with the plurality of forward shelf guiding surfaces 80 a, 80 b, 80 c, 80 d, 80 e and 80 f guiding and limiting movement of the forward shelf 50.

The aft shelf supporting surface 90 of each of the interior surface 60 of the first side wall structure 22 and the interior surface 62 of the second side wall structure 24 together define a lower aft retention location 130 for the aft shelf 52, as shown in FIG. 11. The aft shelf supporting surfaces 92 a and 92 b define an upper aft retention location 132 for the aft shelf 52, as shown in FIG. 12. The aft shelf supporting surfaces 94 a, 94 b, 94 c, 94 d and 94 e define a vertical retention location 134 for the aft shelf 52, as shown in FIG. 13.

The aft shelf supporting surface 94 d is an upright vertical surface. The aft shelf guiding surface 94 e has an arcuate shape that facilitates arcuate movement of the aft shelf 52. Together, the aft shelf supporting surface 94 d and the aft shelf guiding surface 94 e define an arcuate movement path with a position 140 a between the vertical retention location 134 and the upper aft retention location 132, as shown in FIGS. 14 and 15. As shown in FIG. 14, the aft shelf 50 can be moved from the vertical retention location 134 to the upper aft retention location 132 by lifting the aft shelf 52 upward slightly from the vertical retention location 134 and allowing the aft shelf 52 to pivot along the aft shelf guiding surface 94 e to the position 140 a. Thereafter, the aft shelf 52 is lowered from the position 140 a to the upper aft retention location 132, as shown in FIG. 15. The surfaces 94 d and 96 e prevent forward and rearward movement, respectively, of the aft shelf 52 once the aft shelf 52 is in the upper aft retention location 132, as shown in FIG. 15.

In order to move the aft shelf 52 from the upper aft retention location 132 to the vertical retention location 134, the reverse movements are performed.

The aft shelf guiding surfaces 96 a, 96 b, 96 c, 96 d and 96 e define a rear movement path that includes positions 142 a-142 b-142 c between the upper aft retention location 132 and the lower aft retention location 130, as shown in FIGS. 16 and 17. Specifically, in order to move the aft shelf 52 from the upper aft retention location 132 to the lower aft retention location 130, the aft shelf 52 is lifted to the position 142 a (an inclined orientation), as shown in FIG. 16. Thereafter, the aft shelf 52 is pulled gently rearward to the position 142 b until the aft shelf 52 drops downward off the aft shelf supporting surface 92 a, as is also shown in FIG. 16. Thereafter, the aft shelf 52 is slid forward along the aft shelf supporting surface 90 passing forward through the position 142 c (an inclined orientation) until the aft shelf 52 can be dropped to the lower aft retention location 130, as shown in FIG. 17. In order to move the aft shelf 52 from the lower aft retention location 130 to the upper aft retention location 132, the reverse movements are performed.

A description is now provided of the tether clips 48 a and 48 b, and of tethers T with specific reference to FIGS. 18-22. As shown in FIGS. 18 and 19, two tether clips 48 a are located adjacent to the rear seat assembly 32 and are fixed to the floor structure 20 by, for example, mechanical fasteners such as a nut and bolt arrangement or a rivet. Two tether clips 48 b are located on opposite sides of the concealed cargo space 42, and are also fixed to the floor structure 20 by, for example, mechanical fasteners such as a nut and bolt arrangement or a rivet. First ends of tethers T are releasably attached to the tether clips 48 a and second ends of the tethers T are releasably attached to tether clips 48 c located on the forward shelf 50, as described further below. The tethers T are dimensioned such that when the tethers T are attached to the tether clips 48 a and 48 c, movement of the forward shelf 50 is restricted within the cargo area 14. However, the tethers T have sufficient length such that the forward shelf 50 can move easily between the lower, middle and upper retention locations 110, 112 and 114 along the first and second movement paths. As mentioned above and shown in FIG. 6, the deck panel 46 includes recesses 46 a. The tethers T extend from the tether clips 48 a, through the recesses 46 a and up to the tether clips 48 c on the forward shelf 50.

More specifically, as shown in FIGS. 21 and 22, the tethers T attached to the tether clips 48 a and 48 c restrict movement of the forward shelf 50 such that the forward shelf 50 can be easily moved along the first and second movement paths between the lower retention location 110, the middle retention location 112 and the upper retention location 114. However, the forward shelf 50 cannot be removed from the cargo area 14 when the tethers T are coupled to the tether clips 48 a and 48 c. Only after the tethers T are unhooked from the tether clips 48 a and 48 c, can the forward shelf 50 be removed from the cargo area 14 and the vehicle 10, if desired.

Similarly, first ends of the rearward tethers T are releasably attached to the tether clips 48 b and second ends of the tethers T are releasably attached to tether clips 48 d located on the aft shelf 52. The tethers T are dimensioned such that when the tethers T are attached to the tethers 48 b and 48 d, movement of the aft shelf 52 is restricted within the cargo area 14. However, the tethers T have sufficient length such that the aft shelf 52 can move easily between the lower and upper aft retention locations 130 and 132 and can move freely to the vertical retention location 134. As mentioned above and shown in FIG. 6, the deck panel 46 includes recesses 46 b. The tethers T extend from the tether clips 46 b, through the recesses 46 b and up to the tether clips 48 d on the aft shelf 52.

More specifically, as shown in FIGS. 21 and 22, the tethers T attached to the tether clips 48 b and 48 d restrict movement of the aft shelf 52 such that the aft shelf 52 can be easily moved along the rear movement path and the arcuate movement path between the lower aft retention location 130, the upper aft retention location 132 and the vertical retention location 134. However, the aft shelf 52 cannot be removed from the cargo area 14 when the tethers T are coupled to the tether clips 48 b and 48 d. Only after the tethers T are unhooked from the tether clips 48 b and 48 d, can the aft shelf 52 be removed from the cargo area 14 and the vehicle 10, if desired.

A description of the forward shelf 50 is now provided with specific reference to FIGS. 23-30. The forward shelf 50 is preferably made of a rigid foam material coated or covered by a further rigid material such as a plastic, resin and/or polymer material. The forward shelf 50 has an upper surface 160, a lower surface 162 and a handle portion 164. The handle portion 164 is basically an opening that extends from the upper surface 160 to the lower surface 162. The handle portion 164 extends in a vehicle lateral direction (side to side) for ease of gripping by the hand of a vehicle operator, allowing free movement of the forward shelf 50 between the lower, middle and upper retention locations 110, 112 and 114.

The upper surface 160 of the forward shelf 50 also includes first fastening structures defined by apertures 166. There are two pairs of apertures 166, each pair of apertures 166 defining one of the first fastening structures, as described below. As shown in FIG. 23, the apertures 166 in each pair of apertures 166 are spaced apart from one another by a distance D₁.

The lower surface 162 of the forward shelf 50 includes second fastening structures defined by projections 168 and further includes two of the tether retaining clips 48 c, as shown in FIGS. 24-26 and 28. As shown in FIG. 30, each of the projections 168 includes an aperture 168 a. There are two pairs of the projections 168, each pair of projections 168 defining a second fastening structure. As shown in FIG. 24, the apertures 168 a in each pair of apertures 168 a are spaced apart from one another by the distance D₁, corresponding to the distance between the apertures 166.

The forward shelf 50 also includes at least one removable member 170 (a bar member). In the depicted embodiment, there are two of the removable members 170. Each removable member 170 includes a first end 170 a, a second end 170 b and a bar section 170 c that extends between the first end 170 a and the second end 170 b. Each of the first end 170 a and the second end 170 b includes a snap-fitting projection 170 d. Hence, each removable member 170 includes two snap-fitting projections 170 d. As shown in FIG. 26, the snap-fitting projections 170 d are spaced apart from one another by the distance D₁, corresponding to the distance between the apertures 166 and the apertures 168 a.

The apertures 166 in the upper surface 160 and the apertures 168 a in the projections 168 of the lower surface 162 are dimensioned to removably receive and retain the snap-fitting projection 170 d of each removable member 170. The snap-fitting projections 170 d basically define releasable fastener structures dimensioned such that the removable member 170 can be freely moved between two locations: a cargo movement restricting orientation corresponding to attachment to the apertures 166 in the upper surface 160 as shown in FIGS. 27, 28 and 29; and a stowed orientation corresponding to attachment to the apertures 168 a in the projections 168 along the lower surface 162, as shown in FIGS. 24, 25 and 30.

More specifically, when the removable member 170 is installed in the cargo movement restricting orientation (FIGS. 27-29), the removable member 170 extends along the upper surface 160 of the forward shelf 50 and can limit the movement of cargo placed on the upper surface 160 of the forward shelf 50. In the cargo movement restricting orientation, the bar section 170 c is spaced apart from the upper surface 160 and is parallel to the upper surface 160.

When the removable members 170 are each in the stowed orientation adjacent to the lower surface 162 of the forward shelf 50, the removable members 170 are partially hidden from view and are not obtrusive. With the forward shelf 50 in either of the middle retention location 112 or the upper retention location 114, the removable members 170 are easily accessed when in the stowed orientation, such that they can be pulled out of the apertures 168 a and moved to the cargo movement restricting orientation.

With the forward shelf 50 in any one of the lower retention location 110, the middle retention location 112 or the upper retention location 114, and the removable members 170 being in the cargo movement restricting orientation the snap-fitting projections 170 d extend in a vertical direction, as shown in FIG. 27. Further, with the removable members 170 being in the stowed orientation the snap-fitting projections 170 d extend in a horizontal direction, as shown in FIG. 30. In other words, any one of the side surfaces of the removable member 170 can be considered a main surface of the removable member. That main surface of the removable member 170 extends in a first direction with the removable member 170 in the cargo movement restricting orientation and that main surface of the removable member 170 extends in a second direction perpendicular to the first direction with the removable member 170 in the stowed orientation.

The first end 170 a, the second end 170 b, the bar section 170 c and the snap-fitting projections 170 d are all formed unitarily as a single, monolithic element. Further, the first end 170 a, the second end 170 b, the bar section 170 d and the snap-fitting projections 170 d of the removable member 170 are angularly offset from one another such that they define a C-shape when viewed along a side surface thereof.

The removable members 170 have the appearance of being removable handles. However, the removable members 170 are not specifically designed to be handles. Rather, the removable members 170 are specifically intended to be used to limit the movement of cargo placed upon the upper surface 160 of the forward shelf 50.

Further, with the seatback 36 of the rear seat assembly 32 in the upright orientation, and with the removable members 170 in the cargo movement restricting orientation, the forward shelf 50, the removable members 170, the seatback 36 and portions of the first and second side wall structures 22 and 24 define a storage space within the cargo area 14 that restricts horizontal movement of cargo placed on the forward shelf 50.

The forward shelf 50 has a generally rectangular shape, as shown in FIGS. 23 and 24. However, each of the four corners of the forward shelf 50 includes a notch or recess. Specifically, the forward corners include recesses 172 a and the rearward corners include recesses 172 b. It should be understood from, for example, FIGS. 11, 12 and 13, that the cross sectional depiction of the forward shelf 50 is taken at the recesses 172 a and 172 b. In other words, the forward shelf 50 has an overall length that is greater than that depicted in FIGS. 11, 12 and 13. The actual overall length L₁ of the forward shelf 50 is shown in FIG. 11, with those sections cut off by the recesses 172 a and 172 b being shown with phantom lines.

A description of the aft shelf 52 is now provided with specific reference to FIGS. 31, 32 and 33. The aft shelf 52 has an upper surface 180 and a lower surface 182. Reference to the upper surface 180 and the lower surface 182 is relative to the aft shelf 52 being in either of the lower aft retention location 130 (FIG. 11) and the upper aft retention location 132 (FIG. 12). The aft shelf 52 further includes a handle portion 184 and a peripheral edge including edge portions 186 a, 186 b, 186 c and 186 d. The handle portion 184 is defined by an aperture that extends from the upper surface 180 to the lower surface 182. The handle portion 184 is formed adjacent to the edge 186 d of the aft shelf 52.

The handle portion 184 extends in a vehicle lateral direction, side to side, for ease of gripping by the hand of a vehicle operator, allowing free movement of the forward shelf 50 between the lower aft retention location 130, the upper aft retention location 132 and the vertical retention location 134.

The aft shelf 52 has an overall rectangular shape as defined by the edge portions 186 a, 186 b and 186 c. However, the edge portion 186 d has an arcuate or curved contour, as shown in FIGS. 21, 22 and 31. It should be understood that the depiction in FIGS. 11-13 shows the aft shelf 52 in a cross-section taken adjacent to the edge portion 186 c. Hence, due to the curvature of the edge portion 186 d, the cross-section of the aft shelf 52 in FIGS. 11-13 gives the appearance of the aft shelf 52 being smaller. Therefore, in FIGS. 11, 12 and 13, the actual overall length L₂ of the aft shelf 52 is shown with the edge portion 186 d being depicted in phantom.

The curvature of the edge portion 186 d mates with, the curvature of the sill section 38 of the rear hatch opening 28, as shown in FIGS. 2 and 7. Thus, when the forward shelf 50 is in the middle retention location 112 and the aft shelf 52 is in the upper aft retention location 132, the upper surfaces of the forward shelf 50 and the aft shelf 52 are parallel to one another and approximately parallel to the surface of the sill section 38, as shown in FIGS. 2 and 5.

The lower surface 182 of the aft shelf 52 includes two of the tether clips 48 d, as shown in FIGS. 32 and 33.

The shelving arrangement 16 is further explained with the following description of the various combinations of positions and orientations of the forward shelf 50, the aft shelf 52 and the seatback 36, with specific reference to FIGS. 34 thru 53.

In FIGS. 34 thru 43, the seatback 36 is in the upright orientation or seating orientation thereby defining a forward boundary for the cargo area 14. In FIGS. 44 thru 53, the seatback 36 is in the folded orientation, thus extending or enlarging the cargo area 14. In each of the depicted orientations, the forward shelf 50 and the aft shelf 52 extend from the first side wall structure 22 to the second side wall structure 24, and are resting on the shelf supporting surfaces of the first side wall structure 22 and the second side wall structure 24, as described above.

In FIGS. 8, 9, 11, 34 and 44, the forward shelf 50 is in the lower retention location 110 and the aft shelf 52 is in the lower aft retention location 130. In these retention locations, the forward shelf 50 and the aft shelf 52 are co-planar. This configuration of the shelving arrangement 16 maximizes the cargo capacity of the cargo area 14.

In FIGS. 35 and 45, the forward shelf 50 is in the lower retention location 110 and the aft shelf 52 is in the upper aft retention location 132. In this configuration, the forward shelf 50 and the aft shelf 52 are not co-planar. Rather, the aft shelf 52 is slightly higher than the forward shelf 50. Any cargo placed on the upper surface of the forward shelf 50 will have limited movement due to the seatback 36 and the aft shelf 52 being above the level of the forward shelf 50.

In FIGS. 36 and 46, the forward shelf 50 is in the lower retention location 110 and the aft shelf 52 is in the vertical retention location 134. In this configuration, the forward shelf 50 and the aft shelf 52 are perpendicular to one another.

In FIGS. 37 and 47, the forward shelf 50 is in the middle retention location 112 and the aft shelf 52 is in the lower aft retention location 130. In this configuration, the forward shelf 50 and the aft shelf 52 are parallel to one another, but vertically offset from one another. Specifically, the forward shelf 50 is higher than the aft shelf 52.

In FIG. 38, the forward shelf 50 is in the middle retention location 112 and the aft shelf 52 is stowed underneath the forward shelf 50. In FIG. 48, the forward shelf 50 is in the upper retention location 114 and the aft shelf 52 is again stowed underneath the forward shelf 50.

In FIGS. 39 and 49, the forward shelf 50 is in the middle retention location 112 and the aft shelf 52 is in the upper aft retention location 132. In this configuration, the forward shelf 50 and the aft shelf 52 are co-planar. Further, in FIG. 49, the seatback 36, the forward shelf 50 and the aft shelf 52 are approximately aligned (approximately co-planar) such that a back-side surface of the seatback 36 and the upper surfaces of the forward shelf 50 and the aft shelf 52 define an extended approximately planar cargo receiving surface.

In FIGS. 40 and 50, the forward shelf 50 is in the middle retention location 112 and the aft shelf 52 is in the vertical retention location 134. In this configuration, the forward shelf 50 and the aft shelf 52 are perpendicular to one another. Further, the aft shelf 52 serves to box in and enclose an area beneath the forward shelf 50. Hence, the area under the forward shelf 50 is a hidden or concealed storage space.

In FIGS. 41 and 51, the forward shelf 50 is in the upper retention location 114 and the aft shelf 52 is in the lower aft retention location 130. In this configuration, the forward shelf 50 and the aft shelf 52 are parallel to one another, but vertically offset from one another with the forward shelf 50 being higher than the aft shelf 52.

In FIGS. 42 and 52, the forward shelf 50 is in the upper retention location 114 and the aft shelf 52 is in the upper aft retention location 132. In this configuration, the forward shelf 50 and the aft shelf 52 are again parallel to one another, but vertically offset from one another with the forward shelf 50 being higher than the aft shelf 52.

In FIGS. 43 and 53, the forward shelf 50 is in the upper retention location 114 and the aft shelf 52 is in the vertical retention location 134. In this configuration, the forward shelf 50 and the aft shelf 52 are perpendicular to one another. Further, the aft shelf 52 serves to box in and enclose an area beneath the forward shelf 50. Hence, the area under the forward shelf 50 is a completely hidden or completely concealed storage space that is larger than the concealed storage space defined in FIGS. 40 and 50. It should further be understood from FIG. 43, that the back or rearward surface of the seatback 36, the forward shelf 50 and the aft shelf 52 define a completely enclosed storage space between the first and second side surface structures 22 and 24.

As is shown in FIGS. 34 and 42, when the forward shelf 50 is in the lower retention location 110 and the aft shelf 52 is in the lower aft retention location 130, the respective upper surfaces of the forward shelf 50 and the aft shelf 52 are located a distance H₁ above the deck panel 46 (and the upper surface of the floor structure 20). As shown in FIGS. 39 and 42, when the forward shelf 50 is in the middle retention location 112 and the aft shelf 52 is in the upper aft retention location 132, the respective upper surfaces of the forward shelf 50 and the aft shelf 52 are located a distance H₂ above the deck panel 46. As shown in FIGS. 41 and 42, when the forward shelf 50 is in the upper retention location 114, the upper surface of the forward shelf 50 is located a distance H₃ above the deck panel 46. As is shown in FIG. 42, the distance H₃ is greater than the distance H₂. Further, the distance H₂ is greater than the distance H₁.

As shown in FIGS. 22, 43 and 53, with the forward shelf 50 in the upper retention location 114 and the aft shelf 52 in the vertical retention location 134, the aft shelf 52 is entirely beneath the forward shelf 50. Hence, the edge portion 186 d extends up to a point just below the lower surface 162 of the forward shelf 50. In other words, as shown in FIG. 22, an uppermost portion (the edge portion 186 d) of the aft shelf 52 extends below the forward shelf 50.

It should be understood from the drawings and the description herein that the shelf supporting surfaces of the first and second side wall structures 22 and 24 can be modified and re-positioned such that any of a variety of relative retention locations of the forward shelf 50 and the aft shelf 52 can be achieved. For example, as shown in FIGS. 54, 55 and 56 depicting a modification of the first embodiment, with the forward shelf 50 in the upper retention location 114 and the aft shelf 52 in the vertical retention location 134, an uppermost portion (the edge portion 186 d) of the aft shelf 52 extends above the forward shelf 50. The modification to the first embodiment shown in FIGS. 54-56 only show the forward shelf 50 in the upper retention location 114 and the aft shelf 52. The schematic representations in FIGS. 34-42 and 44-52 of the positioning of the forward shelf 50 and the aft shelf 52 also apply to the modification to the first embodiment.
